To all zohom it may concern).-

1 3e it known that I, MAURICE BUCHSBAUM, a citizen of the United States,residing in Ohicago, 1n the county of Oookand State of Illi- 1101s, haveinvented a new and useful Improvement in Invoice or other Files, ofwhich the following is a specification.

This invention relates to the construction of a file or holder forinvoices, letters and other papers.

One object of the invention has been to adapt the holder to be used as apermanent receptacle or holder for the invoices, in which they may bekept as long as desired. The particular style of binder towhichI haveapplied the invention is the one in which the papers are threaded uponvertical wires, and are retained thereon by other wires, the upper endsof which are bent over so as to coincide with and form continuations ofthe filing wires. To this style of binder, I have added a cover which isjoined to the base by an extensible back, so as to adapt the binder touse with a few or with many filed papers.

The nature of these and other features of the invention and theconstruction thereof are fully disclosed in the accompanying drawbelow.

ings and explained in the description given In the drawings, Figure l isa perspective of the holder as it appears when closed. Fig. 2 is a planshowing it open. Fig. 3 is a longitudinal vertical section. Fig. 4 is asection on the line 4-4 of Fig. 3. Fig. 5 is abottom view of the devicesfor shifting the file wires. Fig. 6 is a section on the line 6 -6 ofFig. 5. Fig. 7 is a sectional view illustrating the construction of thefiling and retaining wires at their junction, and Fig. 8 is amodification of the construction of said wires.

In the drawings A represents the base of my improved binder and formingone of the sides of the volume When the binder is full.

B B are the filing wires and O C are the bent over retaining wires. Thelatter are stationary in my construction and are securedin a plate 0fastened to the under side of the base. They are beveled 0d at one sideat their upper ends so they may form a smooth junction with thecorrespondingly beveled ends of the file wires, and so as not tointerfere with the separating movement of the file wires.

The file wires, as already stated, are made movable, and for thispurpose are secured in a sliding plate I), the normal position of whichis adjacent to the plate 0. In order to give room to these plates 5 andc and the lever D of the latter, the under side of base A is cut away asplainly indicated at Fig. 3, and the recess thus formed is closed by aplate a.

The movement imparted to the sliding plate I ing of a lever Dstationarily pivoted at d, and

bearing at its inner end against the studs 01' upon the movable plate.

A stopd serves tolock the lever D in the open position and when thechanges intlie papers have been made the lever is released from thisstop and the plate will then be antomatically returned to its normalposition by the springs D.

A guide 61 may be employed to confine'the outer end of the lever.

The springs tend to retain the sliding plate in its normal position sothat the filing and retaining wires are kept in contact. For renderingthe holder capable of being usedas a permanent file, I provide it with acover E, which when the holder is full, will serve as one side or coverto the volume formed by the file and its contents, the base A formingthe other side as already stated. I also provide the holder with anextensible back F connecting the base and the cover E. This back isflexible and also adjustable at one end so that it is adapted to be usedat all times whether the holder contains onlyafew or many papers. Togive it this adjustability the end which is joined to the coveris'passed in between the boards of the cover and provided with asuitable friction exerting device whereby such end may be held withreasonable firmness after it has been adjusted to suit the thickness ofthe contents of the binder. This friction exerting device consistspreferably'of atransverse strip of metal f around which the end of theflexible back is doubled and a thumb screw f moving in the slot 6 in oneof the boards of the cover, and adapted to draw the strip f firmlyagainst the board and hold it. It will be seen that this clamp can beloosened whenever requisite, to permit the flexible back to belengthened, and then be again tightened, so that as the thickness of thecontents increases the back may be lengthened correspondingly.

In order that the cover may set down closely on the contents at alltimes, it is slotted at e to make room for the filing and re tainingwires. The back is preferably connected to the base and cover at the endthereof opposite the end where the filing wires are located. The holderthus provided with an extensible back may also be provided withextensible filing and retaining wires by adopting some such constructionas that shown at Fig. 8. In this modification the lower ends of each ofthese wires are provided with a friction exerting tube G in which theymay be moved up and down vertically and by which they are clamped withsufficient power to hold them in any position in which they maybeadjusted. This friction maybe obtained by splitting the tubes Glongitudinallyas indicated and bending the metal at the slit inwardagainst the wires. To insure uniformity in the adjustment of both thewires the points of the retaining wire are preferably provided withhooks g and the metal of the points of the filing wires are cut out andbent inward as shown at 9, so that it may engage the hooks 9. With thisconstruction the wires may be raised to accommodate the increase in thepapers filed by putting the finger under the bend of the retaining wiresand lifting thereon.

For the proper classification of the papers as they are put into thefile,I employ the alphabetically lettered sheets I-I shown at Fig. 2.These sheets are lettered both at their outer vertical front margins andalso upon the back side of the vertical margins at their inner or hingededges as plainly shown, so that all the letters are exposed to the userwhen the holder is open as well as when closed, thereby enabling theuser without first closing the holder to turn readily to any lotter ateither side of the place at which it may be opened. These alphabets arealso used with separating or indicating sheets J calculated to dividethe contents of the book into monthly or other periodical filings, thatis to say each alphabet will contain the invoices filed during the month(or other period), and in order that the user may find the invoices forany period readily these sheets are provided with indicating margins jat the top. It is also a matter of convenience to provide the indicatorsheets with end extensions K upon which may be noted in suitable columnsthe names of the parties, the amounts of their invoices, and any otherparticulars desired such as the number of the check given in payment ofthe invoices, or the amount of interest paid, or the folio of the ledgeraccount, the. These records thus become an aid in keeping track of thefirms purchases.

When the file has been filled, it may be placed upon the shelf as anyordinary book is placed thereon, and when thus disposed of it isdesirable that some mark or label be applied to the back to indicate thecontents. A suitable label for this purpose is shown at L and itconsists of a strip of paper, cloth or leather passing vertically aroundthe back and fastened together at its ends upon the inside of the back.

Of course when the filing wires or posts are moved back from theretaining wires by the lever, the filed papers which may be thenthreaded upon them will move with them.

I claim- I. The combination in a tile binder, of separable filing postsand retaining wires located at one end of the binder, and a cover joinedto the base of the binder by a flexible back located at the end of thebinder opposite that at which the posts and wires are located,substantially as specified.

The combination in a file binder, of filing posts and retaining wireslocated at one end of the binder, the posts being capable of a slidingmovement away from the wires, and a cover flexibly united to the base ofthe binder at the end opposite that at which the posts and wires arelocated, substantially as specified.

S. In a file binder, the combined filing wires and retaining wires,having their points in normal contact, and both being extensible toallow the increase in thickness of the filed papers, substantially asspecified.

4. In a file hinder, the combined filing wires and retaining wires,having their points in normal contact, and both being extensible toallow the increase in thickness of the filed papers, andbeing providedalso with means for locking their points together so as to secureuniformityin the extension adjustment, substantially as specified.
